I saw this phrase in a job description last week: Troubleshooting at all layers of the OSI model. That sounds a bit intimidating, right?

Maybe at first. But let’s not overcomplicate it. Once you get past the terminology, it’s a logical way to locate and fix problems. Chances are you already do most of this whether you realize it or not. I was already troubleshooting at at least four of the seven layers when I was working as a part-time desktop support technician in college in 1995.

BYOD is “bring your own device.” It’s the hot new trend in IT, except it’s nothing new. But it was bound to happen, I guess. Companies are tired of buying computer equipment, so they want employees to provide it. And counterculture, nonconformist workers are (I guess) tired of using boring corporate computer equipment. (And here I am, a strong advocate of buying off-lease corporate computers for home use.)

So, since companies don’t want to buy computers, and employees don’t want to use company computers, what’s the problem?

I got the letter this week. The one from (ISC)². If the first word is “congratulations,” it means you passed. But if the first two words are “thank you,” you didn’t. If you want the letter that says “congratulations” in your future, it helps to know how to study for CISSP. Here’s how I studied for mine. Hopefully it will help you. It’s a long road. But it’s doable.
